" y WW 19% Patented Sept. '16, 1952 UNITED STATES PATENT OFFICE v '7 V r e. 126103681 I I DOOR'LOCKING ASTRAGAL v Kurt 1 Tschaepe, New York, N, Y. 7 v v .,idiiplicationFehruary23,1950, sensin 145, 20 i i. 3 Claims.

The present invention relates'to new and use- -iul improvements in door locking devices and more particularly to an 'a-stragal for sealing and locking the edge of a swinging door.

An important object of the invention is to provide a vertical astragal which may be mounted' for horizontal sliding movement at either edge of a swinging door for entering a groove in an adjacent door' structure to lock the door and seal the edge thereof together with-means for automatically retractingthe astragal to release the door for free swinging movement by a predetermined opening force subjected to the door.

Another object of the invention is to provide means for locking the astragal against movement to secure the door in its locked position.

A still further object is to provide a door looking mechanism for double swinging doc-rs and including upper and lower sliding bolts for looking one of the doors and providing a horizontally slidable astragal carried by the other door-for sealing and locking the-meeting edges thereof and also providing means actuated by the astragal to lock the upper and lower bolts of the first named door. v I

A'still further object is to provide an apparatus of this character of simple and practical construction, which is eflicient'and reliable in operation, relatively inexpensive to manufacture-and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being' had to the accompanyingdrawings forming part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 7 is a similar view showing the astragal in sealing position when the doors arelocked, and;

Figure 8 is an enlarged fragmentary vertical sectional view taken on the line 8-8 of Figure l and showing the key controlled lock for the astragal.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the minerals 5 and 6 designate a pair of swinging doors or other double swinging closures, such as French doors, casement windows or the like, the door 5 being provided at its meeting edge with a horizontally slidable vertically extending astragal 1 for entering a vertical slot or groove 8 in the meeting edge of door 6. I Upper and lower slides 9 and Illare slidably mounted in'recesses H and I2 at the upper and lower edges of, door 5 and are connected to the adjacent ends of astragal l by apertured ears [3 carried by the slidesfor receiving pins l4 passing transversely through the astragal and into the opening of the ears. Each sliding block 9 and I0 is provided with arearwardlyextending rod l5 slidable in a guide 16 with a coil spring I! surroundingthe rod or pin l5- and bearing against the rear of the slide to move the slide and astragal outwardly at the edge of the -d 00r. e Y

Each slide'9 and I0 is also formed with a vertical opening 18 in which the upper end I 9 of a bell crank lever 20 is loosely positioned to provide limited playio-r the end IQ of the leverin Lever 20 is pivoted to door 5 by apin 2| and the opposite'end of lever 20 extends in a rearwardly inclined position as shown at 22 and is formedwith a longitudinal slo t 23. The upper bell crank lever 20 for the upper slide 9 is connected to the upper end of a rack bar 2-4 by means of a pin 25 carried by the rack bar and engaged in slot 23 of the bell crank lever and the lowerhell crank lever 26 for the lower slide I0 is connected to the lower end of the rack bar.2'l in a similar manner to rack bar 24.

Rack bar 24 extends downwardly at the free edge of door 5 and rack bar 21 extends upwardly at the free edge of door 5 and are formed with teeth 28 and 29 respectively engaging the di- "ametricall'yppposite' sides of a pinion gear '30 secured to the inner end of a rotary lock cylinder 3| which is rotatably mounted in a conventional type of lock barrel or casing 32 to which the cylinder 3| is locked by a key 33 in the usual manner.

The adjacent ends of rack bars 24 and 21 and pinion gear 30 are mounted in a housing 34 recessed in the central portion at the free edge of door 5, the rack bars being slidable in the housing.

Upper and lower vertically sliding bolts 35 and 36 are p'osi'tioned adjacent the free edge, of -door 6 with the upperend of upper bolt 35' positioned for entering a bolt socket 31 in the header 38 oi the door frame and the lower end of lower bolt 36 being positioned for entering a boltssocket; 3-9 -thepinionflil inthat position.

The doors are locked by turning pinion 44 in a direction to slide bolts 35 and 3-6 in their sockets 31 and 39, whereupon springs I! move slides 9 and lo outwardly of door 5 and rollers 46 and 41 carried by the slides move the bolts 50 inwardly of door 6 to enter notches 54 and lock bolts 35 gand i'sfia e 1 "Pinionisfl is also turned"to"ac'tuate upper and lower rack bars 24 and 21 in a direction to hold slides 9 and I0 outwardly and key 33 then looks The outward movement of slides .9 and ID also mov'es astragal 1 fully into slot 8 to further lock 1; theidoors to each-other.
